+    # violations across 21 files — which is EVERY Swift file in the repository. Nine of the
+    # first ten are `vertical_whitespace_opening_braces` / `..._closing_braces`, i.e. blank
+    # lines, on code inherited from Jaysce/Spaceman and never calibrated against these rules.

+    # So it stays visible and stops being a gate until somebody calibrates it. That is the

+    # applies to the job that was holding the build hostage.
